One of the most common fuel related failures we have witnessed on the LLY Duramax is that of the fuel control actuator. Basically, the FCA is the metering device for the CP3 injection pump.

If the FCA is not working properly, the ECM cannot communicate to the pump how much fuel it should be delivering. In most cases, people first know there is an issue when they have a hard start or no start issue because the FCA will not allow the pump to properly build pressure to start. However, by the time this occurs, the truck has probably been delivering less than the truly desired amount of fueling for a while already as the FCA is a simple spring design that many times takes a rather slow death, and not an immediate failure.

If you're experiencing hard start or no start issues, one easy way to confirm whether or not the FCA is causing the issue is to simply unplug it, thus eliminating any metering. Presuming the truck starts, immediately turn it off as you will have full pressure running to the fuel rail, but at least you have fairly high certainty that the FCA was causing the issue.

This Bosch OE part was exactly as described. It cured my engine surging problem. Shipping was very timely. Thank you Diesel Power Products!

I made the mistake of buying a cheap imitation fuel pressure regulator on eBay. I ordered and installed a genuine Bosch part from Power Products Unlimited and the Duramax is performing flawlessly. I will insist on O.E. replacement parts for my future needs.

Not a Bosch Product
The one I received was not a genuine Bosch product. They told me over the phone it was supposed to be? I'll give them the benefit of doubt that it was a mixup in the shipping department, but either way I will not waste my time ordering these online again. Save yourself the headache and get one from your local diesel pump shop for 50 dollars more and make sure it comes in Bosch packaging with Bosch permanently cast into the black plastic cap. The faulty part is being returned via RMA for a refund so providing DPP refunds the money all is well and no hard feelings.

Shipping error got me the wrong part but DPP fixed it
I ordered the genuine ""bosch"" part on here because the price is great to fix my surging idle on my LLY. Turns out i get a non bosch product in the mail.. i installed it and to my surprise it was worse then the one i had on the cp3 to begin with. After a quick email to DPP they fixed me right up and next day shipped me the correct part. Tyler was great to work with and sympathetic to the shipping issue that their warehouse had made. Don't be lery to purchase this product. It is the genuine part. The customer service is beyond what i would expect from an online retailer.

This is a Bosch unit? Do you have the install kit to go with this??

This is a BOSCH replacement. The o-ring is pre-installed and you will reuse the factory bolts. What is pictured is how it comes.

Is this the actual LLY product pictured? Mine has a 90deg electrical fitting and the one shown does not. I replaced mine with genuine Bosch part but the part failed and need new.?

I believe the fca in that photo is just a generic photo. You will get the correct fca for your truck. In stock ready to go.

Is this the same as the FPR for a 2005 Duramax ? Never heard the term FCA.?

FPR stands for Fuel Pressure Relief on a Common Rail fuel system. The is the FCA ( Fuel Control Actuator ). This is located at the injection pump, with the only electrical wires going to it.
